In someembodiments, the material of the model suit 11 may be elastic fabric orstretchable fabric, such as nylon, polyester, rayon, or spandex.

Referring to FIG. 2 and FIG. 4, an airbag group 13 is disposed on eachsimulation part 12 of the try-on assistant device 10. Each airbag group13 includes a plurality of airbags 131. The plurality of airbags 131 ofeach airbag group 13 is disposed on the corresponding simulation part12. In some embodiments, FIG. 4 to FIG. 6 are cross-sectional views(that is, 4-4 cross-sectional views) of the simulation part 12corresponding to a waist width of the apparel A of the model suit 11 ofFIG. 2. Herein, the airbag group 13 includes four airbags 131, and crosssections of the airbags 131 are elongated, but may also be of othershapes. The model suit 11 has an outer-layer fabric 111 and aninner-layer fabric 112. The four airbags 131 are fixed between theouter-layer fabric 111 and the inner-layer fabric 112, and are fixed bymeans of, for example, stitching, adhesion, or hot pressing, and thefour airbags 131 keep distances from each other and do not come intocontact with each other. However, the foregoing embodiment is merely anexample, and the number of airbags 131 of each airbag group 13 may beadjusted according to actual requirements, and the arrangement manner ofthe airbags 131 of the airbag group 13 may be determined according to anactual application condition, and the arrangement manner may be inshapes of straight lines, curved lines, annular, spiral, or the like.

As shown in FIG. 1 and FIG. 2, the inflating/deflating unit 14 of thetry-on assistant device 10 is connected to the control unit 15. Thecontrol unit 15 may control the inflating/deflating device 14 toseparately inflate or deflate some or all of the airbags 131 of eachairbag group 13. For example, the inflating/deflating unit 14 may be anair pump and is connected to the airbags 131 of each airbag group 13through a plurality of air pipelines 141 (as shown in FIG. 2, herein adashed line is used to represent the air pipeline 141). The control unit15 may be a controller. The control unit 15 may control the volume ofgas of inflation and deflation or the inflation and deflation time ofthe inflating/deflating unit 14, to adjust the inflation degrees of theairbags 131 of each airbag group 13. In some embodiments, theinflating/deflating unit 14 and the control unit 15 may be fixed insideor outside the model suit 11.

As shown in FIG. 1 and FIG. 3, in some embodiments, the try-onprocessing device 20 may be a notebook computer, a desktop computer, oranother mobile communication device. For example, the mobilecommunication device may be a smartphone, a tablet computer, or apersonal digital assistant. For example, the try-on processing device 20of this embodiment is a notebook computer, but this application is notlimited thereto. A consumer may access the Internet through the try-onprocessing device 20 to select favorite apparel A from an onlineshopping platform.

As shown in FIG. 1 and FIG. 3, the input unit 21 of the try-onprocessing device 20 may be a user interface for a consumer to input aninstruction. For example, the try-on processing device 20 is a notebookcomputer. The input unit 21 may be a graphical user interface. Aconsumer may select the apparel A on an online shopping platform throughthe input unit 21 (as shown in FIG. 3, the consumer selects apparel Aherein). A selection action is performed in an operating manner such asmouse clicking, keyboard input, or touchpad tapping, so that the inputunit 21 receives a selection instruction C corresponding to the apparelA.

As shown in FIG. 1 and FIG. 3, the processing unit 22 of the try-onprocessing device 20 may be a central processing unit (CPU), a microcontrol unit (MCU), or a micro processing unit (MPU) having a logicoperating capability. The processing unit 22 is connected to the inputunit 21 and the first communication unit 23. The processing unit 22 mayobtain size information of measurement areas of the apparel A accordingto the selection instruction C, and the processing unit 22 furtherobtains at least one inflating/deflating parameter P according to thesize information of the measurement areas of the apparel A, and outputsthe inflating/deflating parameter P to the try-on assistant device 10through the first communication unit 23. That is, theinflating/deflating parameter P corresponds to the size information ofthe measurement areas of the apparel A. The control unit 15 of thetry-on assistant device 10 may control, according to theinflating/deflating parameter P, the inflating/deflating unit 14 toseparately inflate or deflate the airbags 131 of each airbag group 13,so that the model suit 11 can simulate the sizes of the measurementareas of the apparel A. Further examples are described below in detail.

For example, as shown in FIG. 1 to FIG. 3, before the consumer selectsthe apparel A from the online shopping platform through the try-onprocessing device 20, the model suit 11 (in this example, the model suit11 is a long-sleeve top) may be pre-worn, and when the consumer Aselects the favorite apparel A, a selection action may be performedthrough the input unit 21 (for example, FIG. 3 displays that the apparelA is selected) to generate the selection instruction C corresponding tothe apparel A. Next, as shown in FIG. 7, the processing unit 22 mayexecute step S01 to step S03. First, step S01 may be performed: Receivethe selection instruction C corresponding to the apparel A. As shown inFIG. 1, the processing unit 22 is connected to the input unit 21, toreceive the selection instruction C received by the input unit 21.

As shown in FIG. 7, step S02 may be executed after step S01: Obtain sizeinformation of measurement areas of the apparel A according to theselection instruction C. For example, assuming that the apparel Aselected by the consumer is size M, the corresponding size informationmay include chest/bust width of 102 cm, shoulder across of 45 cm, waistwidth of 63 cm, neckline circumference of 38 cm, sleeve length of 60 cm,sleeve width of 16 cm, and the like. Assuming that the apparel Aselected by the consumer is size L, the corresponding size informationmay include chest/bust width of 104 cm, shoulder across of 47 cm, waistwidth of 65 cm, neckline circumference of 40 cm, sleeve length of 62 cm,sleeve width of 18 cm, and the like. In some embodiments, the processingunit 22 may learn, according to the selection instruction C, the apparelA selected by the consumer, to obtain the size information of themeasurement areas of the apparel A from a database of a merchant throughthe Internet, or an apparel database (not shown) may also be built inthe try-on processing device 20. The processing unit 22 may directlyobtain the size information of the measurement areas of the apparel Afrom the apparel database.

As shown in FIG. 7, step S03 may be executed after step S02: Obtain andoutput the inflating/deflating parameter P according to the sizeinformation, where the inflating/deflating parameter P corresponds to aninflation degree of the airbag group 13 on each simulation part 12 ofthe model suit 11. For example, a database may be built in the try-onprocessing device 20. The database may store inflating/deflatingparameters P corresponding to different size information. Referring toFIG. 1 and Table 1, using the waist width of the apparel A as anexample, assuming that the inflation degree corresponding to fullinflation of each airbag 131 of the airbag group 13 of the model suit 11is 100%, the inflating/deflating parameter P of the airbag group 13corresponding to the waist width 65 cm may be an inflation degree of50%, the inflating/deflating parameter P of the airbag group 13corresponding to the waist width 63 cm may be an inflation degree of60%, the inflating/deflating parameter P of the airbag group 13corresponding to the waist width 61 cm may be an inflation degree of70%, and so on. Alternatively, assuming that inflation time required tofully inflate each airbag 131 of the airbag group 13 of the model suit11 is 10 seconds, the inflating/deflating parameter P of the airbaggroup 13 corresponding to the waist width 65 cm may be an inflation timeof 5 seconds, the inflating/deflating parameter P of the airbag group 13corresponding to the waist width 63 cm may be an inflation time of 6seconds, the inflating/deflating parameter P of the airbag group 13corresponding to the waist width 61 cm may be an inflation time of 7seconds, and so on. That is, smaller size information of the measurementareas of the apparel A indicates a larger inflating/deflating parameterP, to drive the inflation degree of each airbag 131 of the simulationpart 12 corresponding to each measurement area of the model suit 11 tobe higher. The processing unit 22 may output a plurality ofinflating/deflating parameters P to separately correspond to the sizeinformation of the measurement areas of the apparel A, and theinflating/deflating parameters P are output to the try-on assistantdevice 10 through the first communication unit 23.

TABLE 1 Waist Inflation Inflation Size width degree time L 65 cm 50% 5seconds M 63 cm 60% 6 seconds S 61 cm 70% 7 seconds

In some embodiments, a computer program product may be installed in thetry-on processing device 20. The processing unit 22 may load thecomputer program product to execute step S01 to step S03. For example,the computer program product may be an application program stored in acomputer readable storage medium (such as a USB or a memory card), orthe computer program product may also be an application programdownloaded from a network platform (such as App Store run by AppleInc.).

As shown in FIG. 1 to FIG. 3, during first try-on, the try-on assistantdevice 10 may receive, through the second communication unit 16, theinflating/deflating parameter P output by the first communication unit23. Next, the control unit 15 controls, corresponding to a plurality ofinflating/deflating parameters P, the inflating/deflating unit 14 toseparately inflate the airbags 131 of the airbag group 13 of eachsimulation part 12 on the model suit 11, to inflate the airbags 131 tothe corresponding inflation degrees, to simulate the size of the apparelA. For example, referring to FIG. 4 and Table 1, using the simulationpart 12 corresponding to the waist of the apparel A as an example, whenthe apparel A selected by the consumer is size L, the control unit 15may control the inflating/deflating unit 14 to inflate the airbags 131of the airbag group 13 of the simulation part 12 (for example, theinflation time is 5 seconds), so that the inflation degree of eachairbag 131 gradually expands from 0% (as shown in FIGS. 4) to 50% (asshown in FIG. 5), to adjust the tightness of the simulation part 12 tocorrespond to the tightness of the waist of the apparel A of the size L.When the apparel A selected by the consumer is size M, the control unit15 controls the inflating/deflating unit 14 to inflate the airbags 131of the airbag group 13 of the simulation part 12 (for example, theinflation time is 6 seconds), so that the inflation degree of eachairbag 131 gradually expands from 0% (as shown in FIGS. 4) to 60% (asshown in FIG. 6), to increase the tightness of the simulation part 12 tocorrespond to the tightness of the waist of the apparel A of the size M.The airbag group 13 on the simulation part 12 corresponding to othermeasurement areas (such as the neckline circumference, the upper armwidth, and the chest/bust width) of the apparel A of the model suit 11may also be inflated or deflated in the foregoing manner, and detailsare not described herein again. In some embodiments, the control unit 15may also control the inflating/deflating unit 14 to inflate some of theairbags 131 of the airbag group 13 of the simulation part 12, and thisapplication is not limited thereto.

Based on the above, the control unit 15 of the try-on assistant device10 may also record the inflating result information of theinflating/deflating unit 14 (such as the inflation degree or inflationtime of the airbag group 13). The processing unit 22 of the try-onprocessing device 20 may obtain another piece of size information of themeasurement areas of the apparel A according to another selectioninstruction C′, and the processing unit 22 may obtain the inflatingresult information through the first communication unit 23 and thesecond communication unit 16, and re-obtains a new inflating/deflatingparameter P′ according to the inflating result information and theanother piece of size information, and transmits the newinflating/deflating parameter P′ to the second communication unit 16through the first communication unit 23, so that the control unit 15controls, according to the new inflating/deflating parameter P′, theinflating/deflating unit 14 to re-inflate or re-deflate the airbags 131.

For example, referring to FIG. 1 to FIG. 6, and Table 1, during firsttry-on, for example, the apparel A selected by the consumer is size M,the control unit 15 controls the inflating/deflating unit 14 to inflatethe airbags 131 of the airbag group 13 of each simulation part 12 (forexample, the inflation time is 6 seconds), so that the inflation degreeof each airbag 131 gradually expands from 0% (as shown in FIGS. 4) to60% (as shown in FIG. 5). In this case, the control unit 15 may recordthe inflating result information (for example, the inflation time is 6seconds, or the inflation degree is 60%).

If the consumer then wants to have a second try-on of the apparel A, andthe newly selected size is L, the processing unit 22 will first obtain,through the first communication unit 23 and the second communicationunit 16, the inflating result information of the first try-on recordedby the control unit 15. The processing unit 22 then calculates theinflating result information and inflating/deflating parameter of thesize L (Table 1 displays that the inflation time is 5 seconds or theinflation degree is 50%) to generate a new inflating/deflating parameterP′ (that is, the inflation degree is reduced by 10% or the deflationtime is 1 second), and transmits the new inflating/deflating parameterP′ to the second communication unit 16 through the first communicationunit 23. The control unit 15 may control, according to the newinflating/deflating parameter P′, the inflating/deflating unit 14 todeflate the airbags 131 of the airbag group 13 of each simulation part12 (for example, the deflation time is 1 second), so that the inflationdegree of each airbag 131 is reduced from 60% to 50% to correspond tothe tightness of the apparel A of the size L. Similarly, if the consumerselects size S for the second try-on of the apparel A, the processingunit 22 calculates the inflating result information andinflating/deflating parameter of the size S (Table 1 displays that theinflation time is 7 seconds or the inflation degree is 70%) to generatea new inflating/deflating parameter P′ (that is, the inflation degree isincreased by 10% or the inflation time is 1 second), and transmits thenew inflating/deflating parameter P′ to the second communication unit 16through the first communication unit 23. The control unit 15 maycontrol, according to the new inflating/deflating parameter P′, theinflating/deflating unit 14 to re-inflate the airbags 131 of the airbaggroup 13 of each simulation part 12 (for example, the inflation time is1 second), so that the inflation degree of each airbag 131 is increasedfrom 60% to 70% to correspond to the tightness of the apparel A of thesize S. After the try-on ends, the control unit 15 may control theinflating/deflating unit 14 to deflate each airbag group 13 to theinflation degree of 0%, for use of try-on for the next time.

In addition, in another implementation of the instant disclosure, thecontrol unit 15 can also normally operate without the necessity torecord the inflating result information. After the user completes theselection action, the control unit 15 may first control theinflating/deflating unit 14 to adjust the inflation degree of eachairbag group 13 to a preset inflation value (for example, each airbaggroup 13 may be deflated to the inflation degree of 0% or adjusted to10%), and the processing unit 22 may obtain the inflating/deflatingparameter P only according to the size information corresponding to theselection instruction C and the preset inflation value. The control unit15 then controls, according to the inflating/deflating parameter P, theinflating/deflating unit 14 to inflate or deflate the airbags 131 ofeach airbag group 13.

In this way, when the consumer buys the apparel on the internet, theconsumer can actually feel the size and comfort of the apparel A bywearing the model suit 11, so as to greatly reduce cases in which thegoods need to be returned due to wrong sizes, poor comfort, orunsatisfactory styles after the purchase of the apparel, therebyimproving the efficiency and convenience of online shopping and avoidingshopping disputes.

However, for the apparel A of the same size, if materials used (such ascotton, yarn, flax, rayon, polyester, or spandex) or versions of fitting(loose fit, slim fit, long fit, or short fit) are different, thetightness or comfort during actual try-on also differs. Therefore, inanother embodiment of the instant disclosure, the processing unit 22 ofthe try-on processing device 20 may further obtain theinflating/deflating parameter P according to the material parameter,version parameter or both of the apparel A in combination with the sizeinformation of the apparel A, so that the inflation degree of eachairbag 131 of the airbag group 13 of the model suit 11 is furtherapplicable to the apparel A of different materials or versions offitting, thereby further improving the simulation degree of the modelsuit 11. In some embodiments, the size information, the materialparameter, and the version parameter may be separately converted into ann×n matrix according to the arrangement manner of the airbags 131 wheren is the number of airbags 131 of the airbag group 13. It may beindicated as size information

${S = \begin{bmatrix}s_{11} & \ldots & s_{1n} \\\vdots & \ddots & \vdots \\s_{n\; 1} & \ldots & s_{nn}\end{bmatrix}},$

material parameter

${M = \begin{bmatrix}m_{11} & \ldots & m_{1n} \\\vdots & \ddots & \vdots \\m_{n\; 1} & \ldots & m_{nn}\end{bmatrix}},$

and version parameter

$V = {\begin{bmatrix}v_{11} & \ldots & v_{1n} \\\vdots & \ddots & \vdots \\v_{n\; 1} & \ldots & v_{nn}\end{bmatrix}.}$

The n×n matrices may be pre-established, or may be generated throughreal-time calculation according to user requirements. The sizeinformation S, the material parameter M, and the version parameter V arecorrespondingly obtained or calculated by the processing unit 22according to the size, material, and version of fitting selected by theuser, and then the processing unit 22 calculates the inflating/deflatingparameter P according to these parameters. Then the control unit 15controls, according to the inflating/deflating parameter P, theinflating/deflating unit 14 to separately inflate or deflate each airbaggroup 13.

Using FIG. 4, FIG. 5, and FIG. 6 as an example, the airbag group 13 hasfour airbags 131, then n is 4, and the airbags 131 are arranged in anannular shape. The size information S, the material parameter M, and theversion parameter V are separately converted into a 4×4 matrix, as shownin the following Table 2, Table 3, and Table 4. To simplifydescriptions, a diagonal matrix is used as an example in the followingimplementation. The instant disclosure is not limited thereto.

Referring to FIG. 1 to FIG. 6 and Table 2 to Table 4, when the size ofthe apparel A selected by the user is S, the material is cotton, and theversion of fitting is regular fit, the processing unit 22correspondingly obtains the size information S_(S), the materialparameter M_(cot), and the version parameter V_(reg). Then theprocessing unit 22 accordingly calculates that the inflating/deflatingparameter

$P = {{S_{s}*M_{c\; {ot}}*V_{reg}} = {\left\lfloor \begin{matrix}0.679 & 0 & 0 & 0 \\0 & 0.658 & 0 & 0 \\0 & 0 & 0.686 & 0 \\0 & 0 & 0 & 0.665\end{matrix} \right\rfloor.}}$

Then the control unit 15 controls, according to the inflating/deflatingparameter P, the inflating/deflating unit 14 to inflate the airbag group13, that is, the four airbags 131 are respectively inflated to inflationdegrees of 67.9%, 65.8%, 68.6%, and 66.5%.

In some embodiments, two or more airbag groups 13 may be disposed on asame simulation part 12 of the model suit 11. As shown in FIG. 9, inthis embodiment, two airbag groups 13 and 13′ are disposed on thesimulation part 12 corresponding to the cuff part of the apparel A ofthe model suit 11, and the airbag groups 13 and 13′ are separatelydisposed at different positions of the simulation part 12, and comparedwith the airbag group 13, the airbag group 13′ is closer to the openingof the cuff. The control unit 15 may further selectively control,according to the inflating/deflating parameter P, theinflating/deflating unit 14 to inflate or deflate the airbag group 13 orthe other airbag group 13′. For example, the airbag group 13 maysimulate the cuff opening of the apparel A of the size M, and the airbaggroup 13′ may simulate that of the size L. When the consumer selects theapparel A of the size L, the control unit 15 controls theinflating/deflating unit 14 to inflate or deflate the airbag group 13′,and when the consumer selects the apparel A of the size M, the controlunit 15 controls the inflating/deflating unit 14 to inflate or deflatethe airbag group 13, so that the consumer can further sense thedifference of the sleeve length and cuff opening, to further improve thesimulation performance of the model suit 11.

In some embodiments, a pressure sensor 17 may be disposed on an innersurface 132 of at least one airbag 131 of each airbag group 13 on themodel suit 11. As shown in FIG. 4 to FIG. 6, in this embodiment, apressure sensor 17 is disposed on the inner surface 132 of each airbag131 of each airbag group 13, for sensing skin pressure the consumer mayfeel and exerted by each airbag 131, to generate the pressure value. Inan embodiment, when the pressure value is greater than a threshold, thecontrol unit 15 of the try-on assistant device 10 controls theinflating/deflating unit 14 to stop inflating the airbags 131, toprevent the body of the consumer from being excessively squeezed by theairbags 131 and from feeling uncomfortable. Alternatively, in anotherembodiment, the second communication unit 16 of the try-on assistantdevice 10 may be connected to each pressure sensor 17, to output thepressure value to the first communication unit 23 of the try-onprocessing device 20. When the pressure value is greater than thethreshold, the processing unit 22 outputs a stop signal S to the secondcommunication unit 16 through the first communication unit 23. Thecontrol unit 15 of the try-on assistant device 10 controls, according tothe stop signal S, the inflating/deflating unit 14 to stop inflating theairbags 131, thereby reducing the data computation loading of thecontrol unit 15.

In some embodiments, as shown in FIG. 8, after step S03, the processingunit 22 of the try-on processing device 20 may further execute step S04and step S05.

Herein,the display unit 24 is a display screen, and the processing unit 22 maycontrol, according to the pressure value, the display unit 24 to displaythe pressure information. For example, the display unit 24 may displaythe pressure value of each simulation part 12 in text, so that theconsumer can further explicitly learn, from the pressure value displayedon the display unit 24, whether the size is suitable.

In an embodiment, the processing unit 22 may also control the displayunit 24 to display the pressure information by means of colors,patterns, or graphics. As shown in FIG. 10, in this embodiment, thepressure information that the processing unit 22 controls the displayunit 24 to display includes a virtual portrait V and the pressuredistribution information D1 to D5 around the virtual portrait V. In someembodiments, the virtual portrait V includes a front portrait V1, a sideportrait V2, and/or a rear portrait V3 of the consumer. The display unit24 of this embodiment simultaneously displays the front portrait V1, theside portrait V2, and the rear portrait V3 of the consumer. The pressuredistribution information D1 to D5 is indicated in a manner of dots. Thepressure distribution information D1, D2, D3, D4, and D5 respectivelycorresponds to parts of the body of the consumer such as the neck, thearm, the chest, the waist, and the wrist. The density of the dotsrepresents the magnitude of the pressure (for example, sparser dotdensities represent lower pressure, and denser dot densities representhigher pressure). This figure displays that the pressure applied to theneck and the arm parts of the consumer is greater than that applied tothe chest, the waist, and the wrist. In this way, in this embodiment ofthe instant disclosure, the pressure information is presented in avisualized manner, so that the consumer can quickly determine thefitness of the apparel. In other embodiments, the pressure distributioninformation D1 to D5 may also indicate the magnitude of the pressure bydifferent colors, and this embodiment is not limited thereto. Inaddition, the processing unit 22 may also further suggest a suitablesize of the apparel A to the consumer according to the pressure valuesensed by each pressure sensor 17.

Then, as shown in FIG. 8, step S05 may be performed after step S04:Control, according to the selection instruction C, the display unit 24to display the try-on image T. As shown in FIG. 11, in this embodiment,the try-on image T that the processing unit 22 controls the display unit24 to display includes a virtual portrait V and virtual apparel F wornon the virtual portrait V, and the virtual apparel F corresponds to theapparel A. In some embodiments, the virtual portrait V includes a frontportrait V1, a side portrait V2, and/or a rear portrait V3 correspondingto the appearance of the consumer. The virtual apparel F includes afront image F1, a side image F2, and/or a rear image F3 of the apparelA. For example, referring to FIG. 3 and FIG. 11, herein, the apparel Aselected by the consumer is a long-sleeve top, the virtual apparel F isa long-sleeve top corresponding to the apparel A, and the front imageF1, the side image F2, and the rear image F3 are separately combined tothe front portrait V1, the side portrait V2, and the rear portrait V3 byusing augmented reality (AR) technology, so that the consumer canfurther watch, from the display unit 24, the appearance ofhimself/herself with the apparel A putting on, to determine whether thestyle of the apparel A is suitable. In some embodiments, the try-onimage T and the pressure information may be simultaneously displayed inthe display unit 24 (for example, displayed in a split-screen manner),provided simultaneously to the consumer for reference.

It should be noted that although the foregoing steps are described insequence, the sequence is not limited in the instant disclosure, andthose skilled in the art should be able to understand that some stepsmay be performed simultaneously or in a reversed sequence in suitablecases. For example, step S04 and step S05 may be performedsimultaneously, or step S04 is performed after step S05.

In some embodiments, the processing unit 22 may generate the virtualportrait V of the try-on image T in many manners and control the displayunit 24 to display.
